Abstract

We aimed to evaluate the neutrophil lymphocyte and platelet lymphocyte ratios among euthymic adolescents with bipolar disorder (BD) type I. Thirty-six adolescents with BD and 30 healthy controls were included in the study. The diagnosis was made by experienced physicians using the Kiddie and Young Adult Schedule for Affective Disorders and Schizophrenia Present and Lifetime Version and the affective module of Washington University in St. Louis Kiddie and Young Adult Schedule for Affective Disorders and Schizophrenia-Present State and Lifetime. Blood samples were taken during euthymia, which was defined as Young Mania Rating Scale and Hamilton Depression Rating Scale scores below 7. There was no significant difference in neutrophil lymphocyte ratio and platelet lymphocyte ratio between the patient and control group. Considering the literature, we may speculate that in the early stages, euthymia is associated with a lower inflammatory response, and prolongation of BD causes increased inflammatory processes predominant even in euthymia. In pediatric BD, further studies that assess neutrophil lymphocyte ratio and platelet lymphocyte ratio during different mood episodes and that identify neutrophil lymphocyte ratio and platelet lymphocyte ratio changes during the course of the disease will clarify the role of inflammation in the etiology of pediatric BD.
